ASTRO: Arp 82

I hope this isn't a duplicate post but the computer hung up when sending
it the first time and it hasn't appeared on the server.

Arp 82 is an interacting pair of NGC galaxies, NGC 2535 (the big one)
and NGC 2536 its companion. They are about 200 million light years away
from us. Arp classified them in his category: "Spiral galaxies with
companions on arms: large; high surface brightness companions". Though
I wouldn't call NGC 2536 large it is much larger than the companions of
those with small companions. NGC 2535 is classed as SA(r)c pec and the
companion as SB(r)c pec. The (r) indicating they each contain a ring
like structure. Sometimes this can be rather hard to see but not in
these two. In fact if you look closely you will see the spiral arms
come off the rings rather than the core of the galaxies. The field is
rather void of other galaxies except for a lot of very faint distant
anonymous galaxies. The only other galaxy of any angular size in the
image is SDSS J081021.41+250720.2, a red fuzz ball down and right
(southwest) of Arp 82 toward the right edge of the image. It is nearly
twice the distance of Arp 82 at 386 million light years. There are
several quasars in the image as well as three asteroids. The quasars
carry only SDSS identifications that are just their coordinates in the
sky. I've attached an annotated image that points to these three
quasars giving their distance in billions of light years as well as the
three asteroids by their number. They a
(69363) 1994 PK14 at magnitude 18.9
(170765) 2004 CN57 at magnitude 19.5
(83484) 2001 SH93 at magnitude 19.0

A bright star sends in a column of light along the lower edge left of
center. Seems I'm often putting one on the edge of the sensor. Not
sure how I manage that so often. Seeing for this image was awful. A
lot of detail was lost. This winter has been odd in that the seeing has
been either better than normal or far worse but never plain "normal".
